解析目标路径 %q 失败: %w

Error message

解析目标路径 %q 失败: %w

What it means

Thrown by prepareAutoCodeFileTask when filepath.Abs(target) fails to resolve one of the requested output file targets to an absolute path. Each generated file target must be classifiable into the server/web trees, which requires a clean absolute path first.

Solutions

1. Log the %q target and errors.Unwrap to see the OS cause; fix the offending target string.
2. Restart the server so the working directory is valid.
3. If templates were customized, ensure they emit valid relative paths under server/ or web/.
4. Validate the files map keys (non-empty, printable, reasonable length) before calling generation.

for target := range files {
    if target == "" || !filepath.IsLocal(target) && !filepath.IsAbs(target) {
        return fmt.Errorf("invalid target: %q", target)
    }
    if len(target) > 4096 {
        return fmt.Errorf("target too long: %q", target)
    }
}

task, err := prepareAutoCodeFileTask(layout, files)
if err != nil {
    var perr *fs.PathError
    if errors.As(err, &perr) {
        return fmt.Errorf("bad target path: %v", perr.Path)
    }
    return err
}

When it happens

Trigger: Create submits a files map whose key cannot be made absolute — practically when the process working directory is gone (getwd fails) or the target string trips OS path limits; also reachable via prepareRequestFileTask with malformed template output paths.

Common situations: Working directory deleted at runtime; template customization emitting empty or invalid target strings; paths exceeding OS NAME_MAX/MAX_PATH; control characters in generated paths.
